it being wound com-pactly. Plate 27 illustrates three gathering locomotives built bythe General Glectric Co., the center plate and Plate 28 showing themanner in which the reel and motor is mounted. As will be seen,it is mounted on two straight supporting bars bolted to the loco-motive side frames, ^hese bars with the cable guides and the pro-tective resistance of the motor are the only extra parts used, thereason for this being primarily to avoid complicated parts, andsecondly to make it possible to convert any standard locomotiveinto a gathering locomotive. The wiring connections of a standard gathering locomotiveare shown in Plate 29. The gathering locomotives manufactured by the GoodmanMfg. Co. of Chicago, differs very little from the locomotivesdescribed above. The Coodman Mfg. Co. although they now build atwo-motor type of locomotive, advocate a single motor type.

Rheostat Heel 1 TMotor -% Plate 1 20 power is required, the locomotive must necessarily be smaller, andtherefore it is more advisable to build a locomotive with onelarge motor, making generous room for all parts, than to crowdtwo motors into a relatively small space. The roodman Mfg. Co.build one type of gathering locomotive ( see Plate 30; in which amechanical reel is used. Here the reel is driven by.a chain, asprocket being attached on the axle and another on the reel. Thistype is inferior, I believe, to the motor drive because of thefact that a spring is necessary in winding up the cable to keepthe latter wound evenly on the reel; furthermore the chain addsan additional mechanical drive to keep in repair. However forcheapness and for extreme simplicity it is desirable. Where a more expensive equipment is desired, the Good-man Mfg. Co. employ a motor to drive their reel, similar in con-struction to the General Electric Gos, motor. The third type ofreel drive is the spring. This reel
